ROTOLIN Precision Guide Shafts

Precision Guide Shafts


The metric range of Rotolin precision guide shafts have been introduced in response to popular demand. Basically, they represent the sizes of various shafts which were formerly most frequently produced to customers' requirements as "specials". Guide shafts have the advantage of lower costs by virtue of economical large scale specialised production methods and most sizes are normally available for immediate delivery from stock.

It is not always obvious that shafts are an integral part of linear bearing assemblies and for maximum performance, their excellence should match the quality and precision of the bearings. The balls impose searching conditions of service, particularly for pre loaded bearings, and any minor variations in shaft diameter, case depth or surface hardness and finish has a critical influence on working efficiency which can result in tracking or indentations under severe operating conditions. Rotolin guide shafts are made from high grade carbon steel and induction hardened to produce a hard uniform deep case, minimum 60 HRC, free from surface defects or minute cracks They are ground to precision tolerances, straight within 0.025/300mm and parallel with a fine micro finish to ensure a smooth working action and provide the correct preload for the corresponding diameter bearings.

Non-Standard Shafts
It is part of our service to undertake the manufacture of spindles and shafts up to 1828 mm long to customers' special requirements. Non standard sizes and special variations of guide shafts are made to order with prompt delivery.

Cutting Service
Standard guide shafts can be cut to customers' individual requirements subject to a service charge.
